Default rem 760 /30-06 reloading

Would like info on bullet used/oal and how close to the lands when chambered using 30-06.Also will the round fit in magazine?If any of you have the exact inside length of the magazine I would appreciate the info.

This would vary gun to gun. It all depends on the set back of the barrel witch is different for every gun remington put out. They have devices out there that will measure where the lands are to breech end. I know that many state that its ideal for the bullet to just touch the lands for best accuracy. This is somewhat true but not on all models and only applies to bolt action models. A pump action and semi auto may have feed problems when you play with OAL

Helix, with all due respect I think you are mistaken on your explanation of where the rifling starts as it has nothing to do with the what you described as "set back". All barrels start off with rifling from one end to another then the chamber is cut. This causes the distance between the back of the bolt (where the case starts) and where the rifling starts (where the bullet ends) the same or the head-spacing would be off. The "device" that I think you are referring to for measuring the chamber distance are called "go" and "no go" gages.

Bilbo, as for loading for your gun as it pertains to over all length you are limited, having no choice but to load for the length of magazine. Also some guns don't care if the bullet is anywhere near the rifling, the best example is the old (I don't know about new ones) Weatherby rifles were free-bored with the rifling being a long way from the bullet by like a 1/2 inch. Additionally you should not expect to get bolt action type accuracy with your 760 no matter what you do. Again load for your magazine and have fun.

Thanks helix,and Ron,
I don't own the rifle,or have access to it,right now. I guess Ron answered the question I needed,I think.If the oal of any cartridge,even a round nose,fit to the inside dimension of the magazine still won't reach the lands then the only thing I need is that measurement. Bll

Since a pump or semi-auto man-handles ammo and every round except the first one gets at least one and some many rides in the gun when it is recoiling, it is important to crimp the case. It is best to use a bullet with the crimp grove in the right place in order to get to the standard 30-06 COL listed in the manual.

If your bullet of choice has no crimp groove or even if it does the best crimp die is the separate LEE Factory Crimp Die. It needs no crimp groove if set up per the instructions. It is best to size your brass first then trim the brass to the "trim-to" length in the reloading manual. The Lee die is less sensitive to this than the crimp provided in the seating die. The latter requires a crimp groove and that all cases be the same length.

My Remington pump in 35 Whelan shoots about 2 inch groups at 100 yds. That's five 5 shot groups averaged. One group at 50 yds was 1/2 inch but three shots were in the same hole! While not bolt gun accurate, the Remingtons do OK.

You are quite right Ron, thanks for correcting me on this. I don't know what I was thinking on that. I'm still stuck in my revolver brain right now and how you would load a round were the bullet is touching lands in a revolver is beyond me I think I need to go work on something else

Bilbo, file my comments in the trash
